Guide-Seq is a popular method for delineating off-target cleavage activity introduced by CRISPR. First described in Nature Biotechnology, 33:2, 2015, Guide-Seq remains the most rigorous framework to date for genome-wide identification of off-target effects from CRISPR RNA-guided nucleases.

Optional iGUIDE process enables a more accurate assessment of the distribution of dsDNA breaks in cells to help clarify the true cleavage signal. iGUIDE relies on the easy-to-use Guide-Seq NGS method utilizing a longer protected oligonucleotide during the CRISPR process and requires a modified NGS results interpretation software.

Guide-Seq can also be used to identify the location of DNA inserted by transposomes or other insertion methods.

gDNA extraction and transport to Syntezza

Prior to preparing the Guide-Seq library, we can pick up your  samples and perform the DNA  extraction at our facility or you can isolate the gDNA at your lab. DNA extraction service is available from ₪25.00 to ₪40.00 per sample.

If you isolate the gDNA at your lab, we will deliver to your lab the appropriate number of GenTegra tubes required to stabilize your DNA samples for transport to our facilities in Jerusalem and will use GenTegra tubes to safely transport your prepared libraries to the NGS sequencing facility. GenTegra technology enables shipping of DNA samples at ambient temperature without any fear of degradation, sample loss or delay in transport. The cost of shipping and handling is a minimum ₪ 200 for the order, which includes GenTegra DNA tubes for up to 16 samples.

Library preparation

We maintain all of the reagents required for Guide-Seq library preparation at our facility and will use them and prepare your Guide-Seq library for ₪750 per sample.
